Question

After successfully installing Office Home 2024 I cannot open The Word, Excel, PPT apps on my MacBook Air.

Leonie Boyle 0

I have tried multiple times to install Office Home 2024 but each time it completes I cannot open any of the Apps. I get various messages - when an App opens it says I need to purchase and activate Microsoft 365. When I try to open an App in the Microsoft Browser in my account I get the attached.

Thank you for helping.

Hi!

Microsoft 365 is another version of Office—available via subscription—that can also be installed through the App Store. It is likely that you have it installed on your Mac, and it is causing a conflict with the Office 2024 version you purchased.

If you also have older versions of Office, such as 2019, installed on your Mac, these may also cause conflicts.

Follow the steps below:

Go to https://account.microsoft.com/services > Sign in with your Microsoft account > Check if "Office Home 2024" appears in the list.

If it does not appear, redeem your product key at https://setup.office.com using the same account.

Once the license has been validated, close all Office apps > Open Finder > Click on Applications > Drag all Microsoft apps (Word, Excel, PowerPoint, OneNote, and Outlook) to the Trash.

Be sure to also remove any apps that were installed via the App Store.

Restart your Mac and reinstall Office 2024.

If that does not work, download and run the Office for Mac License Removal Tool > Follow the on-screen instructions > Restart your Mac.

This usually points to an activation or old-license conflict on the Mac, especially if Office opens but asks for Microsoft 365 instead of recognizing the Office Home 2024 one-time purchase.

Try this in order:

Verify the license is attached to the correct Microsoft account.
- Sign in to Services & subscriptions.
- Confirm that Office Home 2024 appears there.
- If the license is not listed, the apps will not activate correctly.
Sign in inside an Office app with that same Microsoft account.
- A one-time purchase for Office 2024 still requires sign-in for activation.
- If the app says the account has no license, that usually means the wrong account is being used or an older cached license is interfering.
Remove old Office license files on the Mac, then reactivate.
- This is the recommended step when multiple licenses or an incorrect older license is being picked up.
- It is especially relevant if the Mac previously had Office 2021, Office 2016, or Microsoft 365 installed.
- After removing the old license files, open Word again and sign in with the Microsoft account that owns Office Home 2024.
If older Office apps are still installed, uninstall them before reinstalling Office 2024.
- Old Office installations can conflict with activation and app launch behavior.
- After uninstalling, reinstall from the Microsoft account portal or from m365.cloud.microsoft > Apps > Install apps.
Update Office after installation.
- Close all Office apps.
- Open Finder > Applications > Microsoft AutoUpdate.
- Install all available updates, then test Word, Excel, or PowerPoint again.
- For recent macOS license errors such as Unknown Error 0x0 or License Not Found, Microsoft’s resolution is to update Office and ensure macOS is version 12 or later.
If the installer downloaded but the apps still do not launch correctly, reinstall from the account portal instead of reopening the existing apps.
- Exit all Office apps.
- Go to Services & subscriptions.
- Locate the Office product and select Install.
- Complete the installation, then launch Word from Launchpad and sign in to activate.

If the Mac had a previous Office version before Office Home 2024, the most important step is removing the old license files and then signing in again with the account that shows Office Home 2024 under Services & subscriptions.
